Specification. of Letters Patent.

Patented June 30, 1908.,

Application filed July 23, 19 07. Serial No. 386,187.

To all whom it may concern: j

Be it known that I, MrLToN G. WORTMAN,

, a citizen of the United States, rcsidii g 'at but a slight distanceabove the top of t e car.

shown in vertica The novel features of my invention are hereinafterfully described and claimed.

In the accompanying drawings illustrating my invention, Figure 1 is aside elevation view of a car body equipped with my im proved brake, aportion of theparts being section. Fig. 2.is a top view of the operatingdrum, operating lever,

shown in Fig. 1.

pawl and adjacent parts. Fig. 3 is a longitudinal vertical sectionalview 01 what is 4 is a side elevation of one end of the operating lever.

1 Similar characters of reference denote si1nilar parts.

' 1 denotes the car body from the under side of which swing by soporting links 2 the brake beams 3 disposec at opposite sides of the carwheels 4 and 5.

lvoted to one brake beam 3 is a brake lever 6. A link or bar 7 isconnected at one end to an eye bolt 8 secured to the other brake beam.The other end of said link 7 is pivoted to one end of the brake lever 6,to the other end of which is secured a flexible device, such a rope orchain 9, which is also attached to the periphcry of a rotary drum 10mountedon ahorizontal axial shaft 11 rotatively mounted in bearings 12sup orted on a plate 12 mounted on the roof of't e car. The drum 10 isprovided with two sets of ratchet teeth 13. An 0 crating lever 14 hasone end bifurcated,

't e arms of the bifurcated end having each a slot 15 through which theshaft 11 extends. Said shaft serves as a fulcrum for the lever 14, saidlever having on each arrna lug 16 ads ted to engage the adjacent'set ofratchet test 13. By sliding the lever on its fulcrum, the shaft 11, thelugs 16 may be brought into or out of engagement with the ratchet teeth.Pivoted on a transverse bar 17 which extends through the bearings 12 isa pawl 18 provided with two arms-19 for respectively engaging the twosets of ratchet teeth 13 to prevent rctractive rotation-of the drum 10when the brake is set. Forconvenience of operation of the pawl 18 it isalso provided with two foot rests or arms 20 disposed at opposite sidesof the lever 14. Tlie rope or chain 9 passes from the brake lever 6 toand around a roller 22 supported on a bracket 23 disposed at one end oithe car body near the under side thereof. From roller 22 the rope orchain 9 passes upwardly to and over a roller 24 mounted in a bracket 25secured to the end of the plate 12 near the upper side thereof. Fromroller 24 the rope or chain 9 passes over the top of the car to theperiphcry of the drum. 10 to which th e'rope or chain is secured.

Fastened to the top of the car body 1 is a vertical plate 26 having avertical slot 27 through which 'the rope or chain 9 passes. This plateserves to retain the-rope or chain in position in the, roller 24 and onthe drum 10. In the upper end of the plate 26 is a notch 28 forreceiving the lever 14 when the lever is not in use. .It also serves tokeep the operators hand from striking the roof of the car when the leveris vertically swung, and by retaining the lever out of contact with theroof, the lever will not be held to the roof by ice in freezing weather.

In operating the invention, the lever is first SllL on the shaft 11 sothat the lugs 16 engage the ratchet teeth 13. The lever is jacent wheelsand applying to the wheels the brake shoes 29 carried by said brakebeams.

To release the brakes, the pawl 18 is first released from the ratchetteeth 13 by do ressing either arms 20, at the same time sliding the lugs1 6 out of engagement with said teeth.

My invention may be modified in different ways within the sec e of theappended claims without de arting om its spirit.

Having t. we described my invention, what I claim and desire to secureby Letters Patout is 1- 1. In a car brake, the combination with a brakelever, of a rotary drum having two sets of peri hcral ratchet teeth, anaxial support for sai drum, a flexible device, such as are e or chain,connected. at one end to said bra e said drum, a lever having abifurcated end,
